Globe Control Valve

Pneumatic Balanced Labyrinth Control Valve

Balanced labyrinth control valve features a labyrinth cage with a balanced spool design. The labyrinth sleeve consists of a cylindrical disc with a plurality of coaxial surfaces distributed with a labyrinth. According to the different process parameters of the medium, the different labyrinth diameter specifications and the number of laminated layers are designed to form a cage. The cage divides the total flow passage into a number of small or even stepped throttle passages, forcing the fluid to continuously change the flow direction.
